Water parameters

Temp 76-80 F Temperature

Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.

pH 7.8 - 8.4 potential of Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While less toxic than ammonia, high nitrate levels (above 40–80 ppm) are important to monitor because they can cause fish stress, stunted growth, and harmful algae blooms.

NO2 <0.0001 ppm Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It enables coral growth by supporting skeletal formation, assists in metabolic processes, and ensures that calcium is available for corals, clams, and coralline algae.

SG 1.023 - 1.026 SG Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Pandora Zoanthids

General information

Pandora Zoanthids are an excellent choice for beginner reef aquarists. Many of them caught from deeper locations on the reef. The environment of deep reef species is often challenging to reproduce in the aquarium environment completely. However, in the case of Pandora Zoanthids many hobbyists have had success by placing them lower in the aquarium in a location that receives strong but filtered lighting.

Pandora Zoanthids also tend to do better when kept at more moderate water temperatures ranging from 72° to 76° F. These conditions are recommended as a good starting point when first introducing this species to the reef aquarium. Given time and gradual adjustments, hobbyists should be able to identify the ideal location in which to keep Pandora Zoanthids in their reef aquarium.

Determining sex

Pandora Zoanthids are not batch spawners

Breeding & spawning

It requires moderate light levels combined with medium water movement within the aquarium.

Cautions

Some Zoanthids and Palythoa contain a powerful neurotoxin called palytoxin which can be extremely harmful if it comes in contact with your bloodstream. Take special care handling polyps and avoid handling if you have an open cut on your hands. When handling any type of polyp make sure to wear gloves and protective eyeglasses.
